DC Entertainment chief creative officer and Flash executive producer Geoff Johns was definitive in saying as much at the Television Critics Association press tour on Friday.

“At DC, we really see film and TV as separate worlds,” Johns said.

IGN followed up with Johns after the panel to learn why DC wants to keep them separate unlike Marvel.

“It’s a separate universe than film so that the filmmakers can tell the story that’s best for film,” Johns said. “While we explore something different in a different corner of the DC universe.”

“We will not be integrating the film and television universes,” Johns said definitively.

The CW’s president Mark Pedowitz also talked about the potential crossover from TV to film at the press tour.

“At the moment in time we’ve had no further discussions of whether Arrow or The Flash will appear in any of these movies; that’s up to the studio,” Pedowitz said.

As for whether we’d see a different Justice League on television as versus the movies, Johns said, to a certain extent, yes. Just no Batman or Superman, obviously.

“You’ll see a lot of DC universe characters [on The Flash and Arrow]. You won’t see Batman or Superman. We’re on production on Batman V Superman now. So you’ll see characters like The Atom or Firestorm, but no not Batman or Superman right now [on TV].”

The Flash premieres on Tuesday, October 7, and Arrow returns for season 3 on Wednesday, October 8.
